The drkhtb project was designed with medium to major Internet Service Providers in mind. Featuring extended hashing support, error handling, and simple configuration options, it has proven to be a stable solution for shaping up to 15000 residential
clients with both upload and download rules, it is considered stable and is already in use as a production platform in at least one major ISP running 4 shaping bridges, each handling up to 2 Gbit/s, with a total of 48000 active clients and over 60000 filter rules in each direction. At this point there is no reason to believe that further bandwidth cannot be handled by one bridge, but there have not been sufficient resources to extensively test it. It is believed that up to 4 Gbit/s can be shaped on one individual machine serving at least 20000 clients.
